Basically, we will obtain effective results by making use of the notion of statistical convergence in sense of the power series method which is widely used in approximation theory. With given example, we offer a stronger point of view than the classical meaning and we study the the rates of PP2 -statistical convergence.eninfo:eu-repo/semantics/closedAccessMatrix-valued functionsPp2-Statistical convergenceKorovkin theoremrate of approximationApproximation via power series statistical convergence for double sequences of matrix-valued functionsArticle1614515710.32513/asetmj/19322008233112-s2.0-105002886562Q3WOS:001480123400011Q4
